How to report an installation issue?

[Marcelo Magno T. Sales]

Hello,

I'm trying to install Ubuntu 10.10 from a usb stick and the following 
message is displayed while the system is loading:
"unable to find a medium containing a live file system"

The boot process does not finish. I've googled this error, but have 
found only problems related to flat cables, faulty CD-ROM drives or 
faulty disks, which does not apply to my usb stick. I got this error 
with three different usb sticks, both with Kubuntu 10.10 32 bits install 
and Ubuntu 10.10 32 bits install. On the other hand, I can boot Ubuntu 
9.10 with no problem from the same usb sticks.

So, I would like to report a bug. However, how do I do that? ubuntu-bug 
requires me to have the system already installed. I could report from 
another system, but ubuntu-bug requires me to inform the package where I 
found the error. I don't know which program fails during installation, 
nor what package it belongs to (if indeed it belongs to a package) and 
even if I did, it certainly will not match the package with the same 
name in the system I would use to report the bug (if the package exists 
in this other system).

So, how to file the bug?

Thanks,

Marcelo
